Application filed January 26,1834. (No model.)

and exact description of the invention, suchY as will enable othersskilled inthe art to which it appertains to make and 'use thesame. Myinvention relates to an improvement in gang plows. The plows of thischaracter which have hitherto been made are objectionable on account ofthe great draft required to move them and the diihculty with which thepoints of the plows are held in the exact vertical adjustment requiredfor different depths of furrow. f'

The object of my present invention is 'to overcome these objectionablefeatures and furwork effectively and can be controlled by .the driverwith the greatest convenience and prec ision.

. lVith these ends in view my invention consists in certain features ofconstruction and combinations of parts, as will be fully scribed, andpointedl out in the claims.

In the accompanying drawings, Figure 1 is a side view. Fig. 2 is a sideview. Fig. 3 is a plan view, and Figs. 4 and 5 are detached views..

The main frame, .when two plows forni the gang, consists, essentially,of the three parts a, a', and a", constructed of suitable material,

3 5 and firmly fastened together.- Each of the parts a and c ispreferably constructed of two flat iron rails separated by blocks, toform long vertical slots, which serveto keep the plowstandards fromhorizontaldisplacement. The

4o depending bracket B, consisting of the main arm b andthe bracing-armb, is rigidly secured to thepart a ofthe main frame. To the lower end ofthe marin` arm b the heel of thelandside ofthe plow C is pivoted. Thebracket B is provided with the laterally-extending stud b,

Vwhich forms an axle for the wheel D. The circumference of the wheel Dextends alittle belour the foot of the plow C, and serves to .bear

the weight of this plow and a portion of the 5o main framewhen allowedtorest on the ground. The standard of the plow C extends upward throughthe long vertical slot in the part aof nish a light-draft gang-plowwhich shall do itsy the main frame. The depending `bracket E isconstructed in a similar manner to the brack-l ct B, just described,tothe lower end of the '55 main arm ot' which is pivdtd the heel of thelandside ofthe plow C. The curved lever F has one end pivoted to thebracket E, as shown, and provided with a laterally-extending stud,

e2, which forms an axle for the wheel D. The 6o cuter end ofthe lever Fextends forward and terminates in ahrandle within the convenient reachof the driver. This lever F is lockedin the required positions byresting upon a lug,

a", on the rigid standard a when raised, and in the slot a5, formed inthe rear of -the main frame when depressed. The standard of the plow Cextends upward through the long vertical slot in the parta of the mainframe. The axle G is journaied in boxes suitable for the 7o purpose,secured to the rear portion of the main frame, and is bcntto form acrank at 011e end on which the large wheel D is mounted, and is providedwith an arm, g, at the other.

The rocking shaft H has one endjournaled at 5 or near the center of thesemicircular toothed sector K andthe other in' the adjustable bracket k,the latter being secured to the part a of the main frame. The toothedsector K is pivoted below its center to the part c of the main 8o frameat x, and is provided with curved slots k in the ends of its rim.Through these slots and the part a of the main franiethe bolts k2 pass,and are tightened and loosened by nuts. By inea-ns of these slotsaudbolts the sector K is adjustable in a limited rotary motion about thepivot The rocking shaft l-I is provided with .the arms h and h-one ateach end-and with the lever L and toothed sector Z,.all se- 4cured tothe shaft in such a manner as to turn 9o with it. rI`he end of, thearinh is connected with tht` upper end of the standard of O by means ofan adjustable swivel and pivoted links M. The end of the arm 7L isconnected withthe upper end of the standard of C by the straight link N,pivoted thereto. The lever L is situated within convenient reach of thedriver, and is provided with a spring-depressed dog,` o, situated in aposition to engage the teeth of .the sector l, and a short lever, rooo', pivoted tc the lever L near the handle, and adapted to be operatedby the hand simultaneusly with thelever L. The action of the lever o' isconveyed to the spring-depressed yokes'are swiveled tothe clips r',which are -Y removably/secured tothe parts a and aof the main frame bybolts r2, provided with suitable nutsp', said bolts passing through theparts a and c of the main frame and the side of the clips. The driverssect g/ is mounted ou. the curved band'spring i secured to the rear partof the main frame. z is the foot-rest. The front end of the mainfranieis supported by the wheel D, mounted on `the crankshaped axle S.This axle S terminates in asection of the fifth-wheel s, upon which asimilar section, s', secured to the forward end of the main frame rests,and is secured thereto by the kingbolt t. rlhe king-bolt t extendsthrough the fthwheel s sufficiently far, or is made sufficiently longtopass through a socket, a, in the rear end of the clevis U. rlhe latterterminates in two forwardly-exteiuling arms, each of which is providedwith a vertical socket, u', at its extremity. Aplate, V, terminatingrearwardly in a sleeve, e, and forwardly in 'a perforated bar, o', ishinged vertically between the arms of theclevis by a bolt, r, passingthrough the sockets a and the sleeve o. An adjustable connecting-link,XV, terminates rearwardly in two laterally -perforated chucks, w, thelatter being adapted to embrace the perforated bar e. A bolt, w', isconstructed to pass through the perforations in the chucks w and bar1:',and thereby lock the link V in vertical adjustment. A flat curvedperforated bar or brace, Y, is constructed at one end to embrace thecrank-axle S, while the perforated portion rests on the lower arm of theclevis U, and is constructed to be locked thereto in lateral adijustmcnt by a bolt, yf, which passes through a perforation in Y and theperforation y in the lower arm ofthe elevis. rlhe object of thisadjustable brace Y is to lock the axle in a position a little in advanceof a perpendicular to the fnrrow-line. When the draft is applied, thewheel D will now spring back to its proper position, and the plows willbe held steadily up to the land. The series of perforations in Y enablesthe operator to advance the wheel D3 more or less as the soil to bebroken is heavier or lighter.

The plow is operated as follows: The sector K and adjustable swivel Mare adjusted in such a position that when the levers L and P arevertical, or nearly so, and the lever F thrown forward, the plows willturn a furrow six ir ches deep. rihe notches on the toothed sector K areconstructed at such a distance apart that the movement of the lever Lone notch in either direction will throw the points of both plows eitherdown or up asuiiicient distance to make the furrow an inch deeper `orshallower, as may be desired. By means of the'adj ustable toothed sectorK and the lever L the depth of the furrow may be determined to thefractional part an inch. It will be noticed, furthermore, that the samemotion of the lever which raises or lowers the points of the plows willdepress or elevate the large wheel l)2 by rotating the axle G.

Whenever it is desired to raise or lower the wheel D2 without disturbingthe elevation of the points, it is accomplished by moving the llever Pbackward or forward, and locking it in any required position by thespring-depressed dog in contact with the toothed sector Z.

Vhen it is desired to turn the plow at the end of a furrow or elsewhere,or when going to or coming from the field, t-he plow is readily thrownupon three wheels by moving the lever lL tothe rear and pulling upwardand backward upon the lever F, the plows and wheel D beingby thesemotions raised from the ground. The number of plows is not limited totwo, but may by the same principle of construction be increased to anynumber required.

It is evident that slight changes may be made in the form andconstruction of the several parts of my gang-plow withoutdeparting fromthe spirit and scope of my invention. I do not desire, therefore, tolimit myself strictly to the construction herein set forth.

I am aware that it is not new to construct a ground-wheel to follow andsupport the weight of a plow, and I do not claim such, broadly; but

Vhat I claim as new, Letters Patent, is
